, 9 Claims. (Cl..5-.-299) Fig. 1 is a View in elevation of the invention,.

with a part of the side rail cut away.

Fig. 2 is a view of the invention looking at it from the inside,,taken partly on cross-section line A-A as shown in Fig. 1.

Fig. 3 is a view in elevation of the leg with caster and .the outer. end of;the side rail attached to such leg and showing in particular the plate on the end of the side rail with slots for adjustment and attaching bed ends and providing width adjustment thereof.

Fig. 4 is a view in perspective of an assembly of the invention, showing a cross rail assembled with a bed leg, provided with a caster and a side rail attached, both rails shown in segments.

In the drawings:

I is a bed leg with caster 9 in horn I and the nearly vertical slot IA in its outer flange, IB and 1C refer to the form of the face, or middle portion 8 of one side of the leg IIC referring to the slightly recessed portion and IE to the channel extending lengthwise on the inside of either side of such recessed or middle portion of the face, the end 4B of one part of the cross rail 4 engaging in one of such channels when fixed in position on and in the leg I, 4A is a stud fixed integral on the outside surface and near the end of the cross rail 4 and engages in the slot IA as shown, 4A being driven slightly downward in IA, and 4B engaging in the channel IB, until the cross rail 4 is firmly fixed in and with the leg I. 2 is a side rail firmly attached on and to the top of the leg I, having a normally perpendicularly extending plate 3, with horizontally directed slots 3A, fixed permanently on its outer end. 5 is the other part of the cross rail and joined with 4, to form a complete cross rail by means of the clamp 6, which permits of the adjustment in length of such cross rail.

From the foregoing description and drawing will be readily understood the manner and method of using the invention in the assembling of a bed frame complete for use, however, a further explanation may clarify any misunderstanding of the use of the invention as follows: the caster provided bed leg having an elongated slot extend- -;ing:.;in a lengthwise-and a somewhat diagonal :positionin relation to the edge oftheleg, and the .-.end-of1,the crossrrail which may have a, stud,

with; an enlarged head, :the stud is inserted in .therslot. and forced downward by means of pressure and light blows with a hammer.

.1 By reason of the diagonal or slanting-form of :'the slot IA and the engaging of the end 413 of rail & in channel IB, cross rail- 4 is held firmly againstthe inside of the leg face, thus holding thev leg I and the cross rail 4 together and making distance from the end-ofthe cross rail, asindi- ,cated at. the surface: I0. .Suchend IEI of the a tight assembly-resistant totorque and forces applied from any normal-direction of load.

.fihe end of one face orside of the cross rail 4 is, cutoifrusually at an angle starting a short cross rail l is inthe-edgeof the cross rail 4 not directly-received inone of the channels or grooves ,lBformedin-the leg I, and this cut-off of the end Also plate 3, attached firmlyglto. siderail 2, provides means of attaching upright parts, such as, arm rest, bed end, etc. as desired. Slots 3A in plate 3 provide means of adjustment in Width in conjunction with possible length adjustment of cross rail l and clamp 6, so that any mattress, spring or other structure or fixed dimension imposed or rested on side rail 2 may be held securely.

From the foregoing it will be observed that the entire assembly provide novel and practical means of compact design embodying use of a caster leg and means of holding a caster in place, to provide height and pleasing design and means to receive a bed assembly, a cross rail to provide means of giving adjustable width to assembly, slotted plate providing means of attaching other structure thereto and side rail toprovide means of a platform upon which to rest seating or bedding, all assembled as needed or required without bolts or other fasteners and without tools except possibly a hammer.

We have shown and described our invention in a desired and useful form and structure however, adaptations in its use may necessitate modifications without departing from the basic features or spirit of the invention.

What we claim as new and desire to secure by Letters Patent is:

1. A bed frame comprising a caster equipped bed leg with attached side rail, one flange of said leg having an elongated slot opening extending lengthwise of said leg and somewhat diagonally in relation to the outer edge of said leg, the middle portion of said leg being slightly recessed to form an inside channel along each side of said middle portion, said channels extending lengthwise of said leg.

2. In a device of the class described, the struc:

ture described in claim 1, in combination with a cross rail provided with a stud on its outside surface adjacent to the end and adapted to engage in said slot, said cross rail having one flange projecting slightly beyond the said stud, said cross rail projection adapted to engage in one of said channels to coact with said leg and cross rail to afiect an assembly of said leg and cross rail as shown and described and for the purposes specified.

3. In a device of the class described in claim 2, a slotted plate attached firmly to an end of said side rail, said plate being a means for attaching upright parts to the bed frame, said plate providing adjustment in width of such upright parts.

4. In a frame, a leg of substantially U-shape in cross section and having a base face and a pair of side faces, one of said side faces having a slot therein which slants slightly inwardly of said leg towards said base face, said leg having a vertically extending channel formed therein at the corner between said slotted side face and said base face, a rail member, and a stud on said rail member and protruding therefrom, said stud being engaged with said slot and being movable downwardly thereof to force an end of said rail member to abut against said channel to secure said rail member tightly to said leg.

5. In a frame, a leg of substantially U-shape in cross section and having a base face and a pair of side faces, one of said side faces having a slot therein which slants slightly inwardly of said leg towards said base face, a rail member, and a stud on said rail member and protruding therefrom, said stud being engaged with said slot and being movable downwardly thereof to force an end of said rail member against the inner surface of said base face.

6. In a frame, a leg having a base face and a side face with a slot therein which slants slightly inwardly of said leg towards said base face, a rail member, and a stud on said rail member and. protruding therefrom, said stud being engaged with said slot and being movable with relation thereto to force an end of said rail member into tight association with said leg.

7. A frame as in claim 4 wherein said rail member has a tapered end which is snugly engaged by said side faces upon said rail member being engaged with said leg.

8. In a bed frame, a leg of substantially U- shape in section, a rail, an extension member on said rail, and engaging means on said leg in engagement with said extension member, said NATHAN EUGENE BLANKE. HILLARD J. SANDS.
